If you have one of the new M1 MacBooks, you would know that the battery life on them is incredible. If you do the same thing the next day, you will have discharged a total of 100%, or 1 full charge cycle. Source: Appleįor example, you might use 50% of your battery’s capacity one day, then recharge it fully overnight. A charge cycle can take several days to complete. You complete one charge cycle when you’ve used (or discharged) an amount that equals 100% of your battery’s capacity. There’s something called a charge cycle, which helps explain this process. Now, every time these lithium ions move back and forth, the battery loses a very tiny percentage of it’s total capacity. You want it to stay relatively balanced, and not tip either side too much. Keeping a battery at 100% charge all the time puts stress on the cathode. This results in an even distribution of lithium ions between the anode and cathode. In an ideal world, a li-ion battery likes to stay at 50% charge. The way these batteries discharge is by lithium ions moving from the anode to the cathode through the electrolyte, or vice versa to charge. Energy is stored and released as lithium ions travel between these electrodes through the electrolyte. The anode and cathode are capable of storing lithium ions. Yes, some of the newer MacBooks use a lithium-polymer, or li-poly battery, but for the purpose of this video the difference between them is minimal.Ģ) a separator between the two electrodes andģ) an electrolyte that fills the remaining space of the battery. Traditionally, MacBooks use lithium-ion (shortened to Li-ion) batteries. Let’s start with discussing the battery on your MacBook and the technology behind it.
